Nat was the best host I've ever had on Airbnb - always ready to help when I needed it, otherwise hands off. The condo is really nice with lots of light coming in when you open the blinds. Exactly like pictured. The swimming pool and fitness center are both quite small but I never found them to be crowded either.
It is in an interesting area about 5 minutes away from the Ari Bts station. So you can reach other places more in the center of Bangkok (Siam etc.) quickly. Ari itself feels like it is in the middle of gentrification. It still has street food but also a series of more hip restaurants and coffee shops. Everything is just minutes away from the condo.
